    If you tend to uncompress clear signal, the only way is use HD-SDI equipment.

    I don't think so IP able to compare SDI quality, you may check most guys most vote SDI is better than IPC.
  12. Hello Folks, I wondering have you experience to equip CVI, TVI or AHD DVR at Hybrid and/or Tribrid mode? Particularly in HD Analog + SD camera? Because we find out the SD camera display is not well as on pure SD DVR? If you do is there any methods to shoot this annoy issue? Appreciate any comments, in advance.

    Confusing terms

    SONY EFFIO-E,V, A, P four type of DSP. And you may see SONY website to know how it is. As well, Effio DSP can incoporated with 960H, 760H and 510H depedns on DSP level grade, compatibility and raw produce cost. For SONY EFFIO DSP + 960H no claim exceed 800TVL ( B/W). At present, upto 800TVL analog camera most is (OV, APTINA or SONY) CMOS sensor utilized ISP/DSP.

    Analog HD, HD-CVI, HD-TVI and IP systems

    Brief all three solution is adopt EOC (ethernet over coaxialcable). Basic structure layout for camera is CMOS sensor (OV, Aptina and SONY) + ISP board( Integrate DSP, DAC and EOC) for AHD and CVI but for TVI one more Intersil Board(EOC board).
  21. Yes 2048x1536 is 4:3 ratio and you need to searching 3M even or higher to 5M NVR/NAS. Most important of all is checking IPC compliant list.
